Application med september 9, 1.929.- serial No. 391,391.V

This invention relates to improvements in package vending machines, and more particularly to the mechanism for releasing one package at a time from a stack of packages 5 in a container.`

w15 AnotherA object is to provide a set of opposed dogs for holding the stack of packages up while the bottom package is being released or it drops out, and another set of opposed dogs for releasing the bottom package.

:l 80 Other objects of the invention will bey apparent as the description proceeds.

In this specification and the accompanying drawings the invention is disclosed in its preferredlform. But it is to be understood 5525 that it is not limited lto this form because it mayl be embodied in other forms. It is also to be understood that in and by the claims following the description it is desired to cover the invention in whatsoever form it :.330 may be embodied,

Figure 1 is a sectional side View of the vending machine taken on line 1--1 of Figure 2.

u Figure 2 is a front sectional view taken on line 2-2 of Figure 1.

Figure 3 is a modified form of releasing mechanism partly broken away for purposes of illustration.

.--y o The numeral 1 indicates the casing or housing for packages and operating mechanism. The guides 2, 3, 4 and 5 are flxedto the casing to keep the packages 6 in alignmentin stack form. The rod 9 is mounted in the guides 45 2-3 and carries the depending dogs 7 and 8.

The rod 12 is fixed to the guides 4 5 opposite the rod `9 and carries the dogs 1011.

The dogs have the hook like package support-members 13. i f

Y Mounted Vbelow these dogs on the rodl 14 250 'is a pair of dogs 15* and 116, and on the rod17 isapair of dogs l8an'df19. The rods 14 and V17' being supported inthe guides 2 toinelusive." The 'dogs'15`, 16, 18'an'd19 havehook like package supporting members 20. 55

Pivoted on the bolt 21 in' the casing is the lever.22, vthe movement of which is limited bytheslot'23in the front of the casing. A 'spring 24acts to hold the lever in the raise position. l 1

l Links2?) and 26 pivoted at their outer ends to the dogs v"I" and-10`at27 and 28, andv to the link 29 at 30. The link 29 is pivted to the inner ends of the links 25 and 26 and kto the lever 22 at 31.'v On'thesame pivot isthe g5 pendant link 532and it has' the pivot .33 at its lower en'd to which the links l34 and 35 are attached; The outer'ends of these links .are pivoted at 36 and 37 tothe dogs 16 'and 18.

When thelever 22 is in the raised position :p70 the 'links act to pull the upper dogs in, and

push the lowerdogs outas shown in Figure 1. The upper dogs hold up the stack I of packages and the lower dogs release the'lbottom package where it falls near the opening-'175 38lin-thecasing where it can be picked up.

I yThe above described vending mechanism l'wouldoperatetofrelease one package 'at a time free, but provision is madefor 'coin release ofthe lever by means of the coin chuteifo The lever is lockedl inthe' 'up position by the latch 40 pivoted at. 41, and it has the shortv arm 42 inthe pathfof downward motionof j-the arm 43,- which arm receives the coin and` S5 -1 aprojection 44 on the lever presses-down on the coinand carries the arm 43 down which releases the latch 40 and allows the'lever to move down and operate the package releasing device; un

In the Inodied form shown in Figure 3 45 indicates the casing, and 46 and 47 the package guides. 48 is t-he hand lever which is held in the raised position by the spring 49 and pivoted on the casing at 50.

A link 5l is pivoted onthe lever at 52,

and this lever has the links 53 and 54 pivoted on its upper end at 55.

These links are pivoted at their outer ends at 56 and 57 to dogs 58 and 59 pivoted on the rods 60, 6l in the brackets 62. 0n the casing spaced from the dogs on the rods,y are the duplicate dogs 63 and 64. Y

Each dog has the inturned catch 65. on the lower end, and the pivotedfriction stop 66 at the upper end. This form may have the same means for locking the lever and the releasethereof by a coin, but it is not shown in this instance as the modifica-tion relates to the package release means only.

Theoperation of the coin release-and kpackage delivery .shown in Figures 1 vand 2 is as follows: f

The coin is inserted inthe coin slot and dropsdown the chute 39 and rolls out-at the bottom onto thelever 22, which is now pressed down carrying the coin and arm down" with the lever on the pivot 2l` the arml comingl in contactwith the projection 42 on the latch 40 throws the latch out of the path of motion lof the lever and allows it to continue moving, and through the li'nk 29 pulls the links 25 and 26 downto a straightposition thereby pushingout the dogs connected thereto and releasing the pile of packages. at the same time through the link 32'the links 34 and 35 are pushed down pulling in the dogs' connected with these links' and catchingv the descending packages. Y

When the lever is released the sprinrvpulls it up which action throws the lower dogs out and releases the package. and throws the upper dogs to hold the stack of packages.

IVhile in the above description, packages are stated as the article vend'ed, it'will be seen that the' device could be made large enough for any size package, and small enough lfor anyl single article.

' Having thus descrihedmv invention. what I' desire to secure bv Letters Patent of the United States is asl follows, but modifications mav hek made in carrving out the invention,

and in the annexed drawings, as defined by the claims: Y

1. A vending machine' comprising ai casing having a magazine to receive alstack of packages, a plurality of opposed dogs pivoted in said: casing and adapted to engage the'lowermost package, a toggle-joint' connecting said dogs', a second set of dogs pivoted in said casingY and adapted .to engage the adjacent package, a second toggle joint connecting said dogs, and means to operate said toggle joints A synchronously.

2. A vending machine comprising a casing having a magazine to receive a stack of packages, a plurality of opposed dogs pivoted in said casing and adapted to engage the lowermost package, a toggle joint connecting said dogs, a second set of dogs pivoted in said casing and adapted to engage the adjacent package, a second toggle joint connecting said dogs and holding said dogs in a reverse position in respect to the first dogs, a link joining said toggle joints, and operating means for said link.

In testimony whereof I have hereunto set my hand this 5th day of August A. D. 1929.
